How is the 60m coming along? Do you have a decent way of timing yourself. A really impressive goal, interested in seeing your mechanics at top speed. I tried to increase my squat frequency although I don't have near your work capacity and also have problems with recovery because of track work... BUT... moved squatting from 1-2X week to 3-4x week. Only problem is anything greater than singles with more than 350 gives me low and mid back soreness that ruins me for a few days are ruins the next workout. For example Wednesday was 3x315,3x3x365 paused... Today my back hurt too much to front squat more than 245. Have you ever dealt with back soreness like this? Does it go away? Weirdly my legs seem to adapt just fine and stay in a sort of sore but tight state which doesn't hinder training but my back just gets tighter and hurts more and more.
- my acceleration has been improving a lot with the contrasting sled drags + sprint workouts. calves, glutes and quads got bigger. no formal timing yet. im doing my GPP type training on my own. i will not have time to train and get solid top speed mechanics. plan is to go apeshit on the acceleration and hopefully by the time it decays, the distance has already been covered in decent time. 60m is just 1 test.
- yes, sprint training is very draining. one thing i learned lately is that it is very difficult to make a sub-max workout in sprinting.. its mostly all out all the time. the only way to control intensity is to not do it often. my squat dropped from 440x1 top sets for 14+ days to a barely 400-410x1. i felt so weak in the squat it was not cool at all. the strong is coming back again and by sun-mon.. il be back to paused 440 again.
- front squats really require strong spinal erectors to keep the torso solid. with the way i do my back squats, i rely also a lot on keeping my torso solid and upright. my secret is the GHR (at home) - weighted back extensions in the mid-high rep range. i do it whenever it feels right. high rep 135s then chug down protein shakes. my spinal erectors got massive just from those.
- yes, tight/sore legs does not mean a bad squat workout. in fact, i usually lift heavier when i have some sort of that quad lock feeling. sore lowerback and everything is mush, squat strength at least -30 to -40lb easily. i actually thought that the floor was uneven at one point because i cant seem to keep everything solid..
- sore lowerback: use smith machine bar to foam roll yourself. find a way to dig deep into the muscles. good luck on your training. i like sprinting. i don't like how it kills the squats if you over do it.
